Specification forming part of Lcttcrs Patent No. 17,262, dated May 1'2, 1857.

Massachusetts, and SIL'AsEDWIN Gnasn, of

Qharlestown, in the county of Middlesex and.

State aforesaid, have invented certain new and useful Improvements in Machinery for Making Lozenges, or stamping sundry forms or articles out of thin sheets composed of. one or more materials; and we do hereby declare that the same are fullydescribed and represented in the following specification and accompanying-drawings, letters, figures, and references thereofi Of the said drawings, Figure 1 denotes a Fig. 2 is an elevation of one side of it. Fig. 3 is an elevation of the other'sideof it. Fig. 4is a vertical and longitudinal section of it,'thc same being taken on a plane supposed to pass through one of the stampers of the shapingcylinder, to be hereinafter specified. Fig. 5 is avertical and transverse section taken throughthe axis of the shaping-cylinder.

' Such other figures asmay be necessary to aclear representation of our improvements will be hereinafter referred to and described.

. In the saiddrawings, or in such of them as .it is seen, A represents the frame for supporting the operative parts of the machine.

Bis the main driving-shaft, to which the moving power is applied in any suitable manner. 1, 3,) fixed ,upon it. Around this pulley and another pulley, c, conveys motion to thepullcyc and to a roller or drum, (I, placed on the shaft of the pulley 0. An endless apron, G, traverses around the roller (1 and anothencyliudric roller, 6, ar-, ranged as seen ,in Fig. 4.

Beneath the 'roller 0 four other cyliudric 1ollers, D, E, F, and G, are arranged, as seen in Fig. 4, and two endless aprons, K and L,-

are made to pass around and be supported by the rollers F and G and two other rollers, H

y and I, as seen in Fig. 4, the ends of the rollers D and Ebeing made to rest against two vertical and parallel plates or planks, 1 1?. The several rollers D E F G receive their motions in the directions denoted by arrows thereon in Fig. 4, such motions being produced by the following-described or any other proper mechan endless band, b, operates, 'and' anism. The cylindric rollcr'G is fixed on the driving-shaft B, and of course is revolved by and with it. A gear, f, fixed onone end of the driving-shaft, engages with another gear,

g, fixed on the shaft of the roller F, and thereby imparts motion to the roller F; The endless aprons K'and L,'passing around the rollers F andG, as a matter of course, are moved by them. I

The mass of lozenge-paste from which the lozenges-are to be cut is placed on the top of the apron C, by which it is conveyed to and presented between thetwo series of rollers D E and F G. As'it passes downwardb'e'tween these two series of rollers and the endless bands K and L they reduce it to the thickness required for the lozenges to be cut from it. Previous to such reductions of the mass to an equal and proper thickness a quantity of'very finely powdered'su'gar is placed on top of each and the rollers D and E are apron K and L,

brought down to within a short distance from their respective aprons, such as will allow a very thin stratum of sugar to pass out be tween each roller and its apron and to be laid by it on the surface of the sheet of paste. Such powdered sugar prevents the paste from adhering to the aprons of the machine. Therollersl) and E revolve in dircctionscontrary to those of the upper parts of their respective aprons L and K. Consequently the rollers D and E not only serve the purpose of directing the paste to or between the reducing-rollers F and G, but they also serve to prevent compression of the sugar on the belts and regulate the thickness of the stratum which passes out from betweentheni and their belts.

To the journals of each of the rollers D'E suitable elevating and depressing screws, h h,

. should be applied in such manner as to enable each of the rollers to be elevated to such distance above-its belt as may be desirable, and each of the said rollers is put in motion by suitable gears connected with the drivingshaft, or by a pulley, & or k, on the axle of each roller, an endless band, Zorm,-passing around eaehpulley t or k, and a pulley, n or o, as seen in Figs. 3, 1, the pulley 0 being fixed on the shaft of the roller F.

The dough or sheet of paste'as it emerges from between .the two aprons K L is received upon a conveyor or endless apron, O, which runs around two cylindrie rollers, M and N, such apron 0 being put in motion by suitable mechanismviz., a pulley, p, (on the shaft of the roller M,) and an endless belt, q, made to pass around the said pulley, aiul'anotherpulicy, r, situated on the shaft of the roller 0 The apron O conveys the sheet of paste or dough, as it is generally termed, to the stamping-cylinder or apparatus. (Seen at P.) The said stamping-0y]inder has thejournalsof its shaft 8 supported in suitable boxes, ft, and is arranged as seen in the drawings. It is composed of two circularhcads, u u, fixed on the shaft, and united together by a series of crossbars, 12 r r, &e.

To each of the bars 0 a row of tubular eylindric or other proper shaped cutters. m .2" .r, is screwed or otherwise properly attached,

such cutters being arranged as seen in Fi s.

b 4 and 5. A small lllht'Ol: or dlseharger, y of a S120 corresponding to the interior of this tubularcutter,isplaecd within each ofsueh cutters, and supported on a rod or stem, the

several stems ofeachstraight row of pistons being fastened to and made to project l'ronr'a long bar, whose ends pass through radial orifices made through the two heads u u of the cylinder 1, as seen at I) in Fig. ti, which is a side view of one of the heads as detached from its shaft. Each r'f'the'bars a rests at its ends upon springs c c, and when the said bar is forced against the outer ends of the orifices I1 71 of the cylinderhcads u u the outer surfaces of the several pistons y y 7 connected to it are brought into the piano of the outer or cutting edges of-their respective cutters x x w. The purpose of the pistons is to discharge the lozenges from the-cutters at the proper time, and by an operation which will be hereinafter described.

In connection with each straight row or series of cutters, "a scrap clearer or discharger is used. It consists of a bar orplate, d,made with orifices through it of a diameter or size to receive the cutters, the same being seen in Fig. 7, which is a side view of the cylinder]? as it appears when detached from the rest of the machinery. Thescrapclcarers are niadcso asto be capable of being moved freely a short distance toward and away from the axis of the cylinder, and they eachrest on and are pressed outward by two springs, c c. The ends of the several clearer-s extend, respect ively, underneath two flanges, f f, Fig. 9, which project from the inner sides of the ('ylinder-heads and from the outer surface, and near the ends of eachclearcr two studs, It h, extend, as seen in Figs. 5, 7, and 9. Each circular row of studs 7. acts in connection with a curved circular are or bar, 1', arranged over it, as seen in Figs. 1, i, 5, and El, and fastened to the frame A. The rotation of the cylinder P is in-thc direction denoted by the arrow 9 in Fig. .L. The inner surfacc of that end of each of the circular arcs or bars 2" i which is nearest to the roller H is flared outward or beyond the circular curve, as seen at k in scrap dischargers or plates from which they project will be depressed below the outer ends of the cutters a distance equal to the thickness of the sheet of lozenge-paste. As soon as the projection k of each scrapwlcarcr passes beyond the ends a of the two curved bars ii the clearer will be suddenly and smartly thrown or forced outward by the springs and against the flanges f f,and so as to cause the scrap of pa te or dough resting on them and 'innnediately around the cutters to be thrown off and down upon an endless dischargingapron, Q, arranged as seen in Figs. 1 and 4,

-.and supported on two cylindric rollers, 0'1),

and a horizontal rest table or board, q, extended between the sides of the frame. Such endless apron has a movement given to it in the direction denoted by t-hearrow 1" thereon, (see Fig. 4, and it is put in motion by means of an endless band, 5-, which passes around a grooved pulley, t, (fixed on the shaft of the roller 0',) and a pulley, a, fixed on the shaft of another cylindrie roller, 11, disposed as seen in the drawings.

The cylinder 1 is put in rotation by means i of an endless chain, 10, which passes around two toothed gears or pulleys, w 1, one being fixed on the driving-shaftl) and the other on the shaft of the cylinder P. Therc is also on the shaft of the cylinder 1 agroovepulley, z, around which and. a pulley, a, fixed on the shaft of the roller '0, an endless band, 6 works and communicates motion to the roller o and to an endless apron, R, which traverses on the roller o, another roller, 0, and a horizontal plank or table, (if, all arranged together and with respect to other parts of the machinery as seen in Fig. 4.

As was hercinbefore described, eachlateral or straight row of pistons 1 y 7 is supported on a bar, a. In connection with such bars a two curved stationary semicircular arcs or bars, 0" a", made h'kethc bars 2" i, are used. They are fastened to the frame A and rest directly over thcends of the bars a, and are to hem placed as to cause the bars to be moved inward or toward the axis of the cylinder. at a proper timethat is, juice before or immediately after any of the straight rows of cutters passby the roller N While the bars are moving in contact with the inner surface of the arcs or bars 6" e, the pistons are deprcsscd to their greatest distance below the edges of their respective cutters, and it is at such times that the spaces between the outer edges of the cutters and outer plane surfaces of the pistons are filled with paste or dough, which has been struck or forced into the-springs against which it rests are relieved and force'the bar suddenly forward or ,outward and against the outer ends of its orifices b b, and so as to discharge the lozenges from the cutters and cause the said lozenges to fall upon the endless apron Itor asmall-thin board placed thereon, and moved by and with the .endless apron.

v It 'was before stated that the scraps or waste dough were thrown upon the endless apron Q. By the movement of such apron they are carried againstabar, f directly'underneath and against which the upper surface of the apron passes. This bar is not placed at a right angle to the sides of'the frame A, but is arrangedat an acute angle with one or both sides of it, as seen in Fig. 1. It consequently causes i the scraps to be directed and moved toward, into, or through an openingor P 0',

madcthrough'the side of the frame and ma level with the-top of the 'apron Q.' .As they are discharged from the opening'they may be received into a suitable receptacle placed underneath it, and on the floor on which the machine may stand. The scraps are thus received and carried off on one apron,whi1e the lozenges are received and carried off on the other. It is, however, customary v to have a series of boards, each of about onethird the length of the machine, such boards being regularly laid on the endless apron R at one end and taken off at the other end; and after they have passed'underneath the cylinder 1 and received the'lozenges ontheir upper sur-. face, such boards are afterward removed to and placed in racks or stands for the pur pose of suffering the lozenges to dry by exposure tothe atmosphere.

The next part of the machinery to be de-. scribed is the striker. It consists of a block of wood or other proper material, S, arranged over the cylinder P and attached to a horizontal rocker shaft, h", by two arms, 1" i." The said rocker-shaft, is supported in boxesk'ik, and has an arm, l, proj end of it and jointed to one arm-o f a bent lever, m, which turns upon a fulcrum, n. The opposite arm of such lever acts in connection with a Series of pins, 0 0", extended from the side of a circular plate, '1), which is fastened on'the shaft of the cylinder P and revolwes with such cylinder; The said arni is borne up against any of such pins against which it may be by a spring, q. around in a circle and at'equal distances apart, and as each one is moved around it so wa ates the lever m as to cause the strikerto be elevated and set free,so as to be thrown back or down by the recoil of the spring q. The striker is so actuated every time a straight- The pins yo 0 are set row of cutters is brought directly under it, and it-strikes uponthe sheet of dough or paste and forces it down upon the cutters in such manner as -to}c, ause them to pass through it. In advance of the striker afle xible roller or cylinder,T,is placedagainst the cylinder 1?, and so as to roll against and compress the dough into the cutters and compact the snrfa cc of the lozenges. A" cylindrical brush, -V,' may be placed against the surface of thefiexible roller and set in motion byanyproper means, so as. to remove any surplus sugar which might accumulate thereon.

of the cylinder P may be somewhat greater than that of the'apron 0,- it being such 'as-will bring each straight row of cutters close up against the cuts on the paste made by the pre ceding r w, or that which had just before acted on the paste;

Having-thus described our machine, what we claim therein 'is as follows:

endless apron K L, and the sugar-receptacles formed by the endless aprons, the two rollers D I l, and the side plates or timbers of the, frame A, the whole being for the purpose of reducing the dough or mass of pastc'to an equal thickness and applying strata of powdered sugaror material to its flat surfaces, as described.

2. The striker and its operative mechanism as combined with the cylinder P and niade to operate in connection therewith, essentially in manner as hereinbefore specified, not meaning to claim arroller as combined with the cyl- -inder for simply forcing the dough into the cutters by pressure, but a contrivance like the striker, which forces the dough into the cutters and the latter through the dough by a blow or percussion, as described;

3. In combination with the cylinder of ,cutters 'and the striker, a flexible or elastic roller,

.of the lozenges after the action of the striker has taken place.

cutters, pistons, andscrap-c'learers, andtheir operative mechanism, the two endless ,aprons out of the machine, substantially in the mau nor as specified. V
